RedHat 9 (Linux i386) - man page for getsockname (redhat section 2)

GETSOCKNAME(2)			    Linux Programmer's Manual			   GETSOCKNAME(2)

NAME
       getsockname - get socket name

SYNOPSIS
       #include <sys/socket.h>

       int getsockname(int s, struct sockaddr *name, socklen_t *namelen);

DESCRIPTION
       Getsockname  returns  the  current  name  for the specified socket.  The namelen parameter
       should be initialized to indicate the amount of space pointed to by name.   On  return  it
       contains the actual size of the name returned (in bytes).

RETURN VALUE
       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

ERRORS
       EBADF  The argument s is not a valid descriptor.

       ENOTSOCK
	      The argument s is a file, not a socket.

       ENOBUFS
	      Insufficient resources were available in the system to perform the operation.

       EFAULT The  name  parameter  points  to	memory not in a valid part of the process address
	      space.

CONFORMING TO
       SVr4, 4.4BSD (the getsockname function call appeared in	4.2BSD).   SVr4  documents  addi-
       tional ENOMEM and ENOSR error codes.

NOTE
       The  third  argument of getsockname is in reality an `int *' (and this is what BSD 4.* and
       libc4 and libc5 have).  Some POSIX confusion resulted in the present socklen_t.	The draft
       standard  has  not been adopted yet, but glibc2 already follows it and also has socklen_t.
       See also accept(2).

       bind(2), socket(2)
